For years, SEO has focused heavily on one question: Is my website indexed by Google?
But AI-powered search is changing the way we think about website visibility.
A webpage can potentially be discovered and cited by ChatGPT even if it isn’t indexed by Google.
So how is that possible?
ChatGPT Doesn’t Rely Only on Google
ChatGPT has its own web-search and retrieval infrastructure and can also use external search sources.
OpenAI operates OAI-SearchBot, a crawler used for search discovery. Independent research from Peec AI has also identified a retrieval source called “Labrador”, which researchers associate with OpenAI’s web retrieval infrastructure.
However, OpenAI has not publicly confirmed “Labrador” as the official name of a standalone search index.
The important takeaway is simple:
ChatGPT does not necessarily see the web exactly the same way Google does.
Different search systems can have different crawlers, indexes and retrieval processes.
Google Indexing ≠ ChatGPT Visibility
Consider a simple example:
| Search System | Page Status |
| Not indexed | |
| Bing | Indexed |
| ChatGPT retrieval | Discoverable |
| ChatGPT | Potentially cited |
A page that Google hasn’t indexed may still be discoverable through another search or retrieval system.
However, being discovered does not guarantee a citation.
There is a difference between:
Discovery → Retrieval → Understanding → Citation
ChatGPT may retrieve information from a webpage without ultimately citing that webpage.
Why This Matters for SEO
Traditional SEO focuses on metrics such as:
- Google rankings
- Organic traffic
- Impressions
- Click-through rate
- Indexation
- Backlinks
AI search introduces another layer:
- ChatGPT citations
- AI search visibility
- Brand mentions
- AI referral traffic
- Visibility for conversational queries
A website could rank well on Google but not appear in AI-generated answers.
Likewise, a website could potentially receive an AI citation without having a strong Google ranking for the same query.
This means Google SEO and AI SEO overlap, but they aren’t identical.
How Can You Improve AI Search Visibility?
There is no guaranteed formula for getting cited by ChatGPT, but many traditional SEO fundamentals remain important.
1. Keep Your Technical SEO Strong
Make important pages:
- Crawlable
- Accessible
- Properly indexed where appropriate
- Internally linked
- Correctly canonicalized
2. Check AI Crawler Access
Review your robots.txt configuration and make sure you understand whether OAI-SearchBot can access the content you want to make available for ChatGPT search.
3. Create Useful, Direct Answers
Create content that clearly answers the questions your audience is asking.
Instead of focusing only on keywords, consider conversational questions such as:
“Can ChatGPT cite a website that Google hasn’t indexed?”
Clear, useful answers are easier for both users and search systems to understand.
4. Publish Original Information
Original research, case studies, data, experiments and first-hand expertise can give your website information that is genuinely useful to others.
Is Google SEO Still Important?
Absolutely.
AI search isn’t making traditional SEO irrelevant.
Google remains an important source of search visibility and traffic.
The difference is that SEO professionals now have more search ecosystems to consider.
Instead of thinking only:
“Does Google index my page?”
we should increasingly ask:
“Can search and AI systems discover, understand and use my content?”
The Future of SEO
Search is becoming more distributed.
Google has its own search infrastructure. Bing has its own. AI search systems can use external search providers while also developing their own retrieval and crawling capabilities.
As a result, different systems may discover and surface different webpages.
The key lesson is:
Google indexation is important, but it is not the same thing as AI visibility.
For SEO professionals, the future is not about choosing between traditional SEO and AI SEO. It’s about understanding how content can become discoverable, understandable, useful and citable across different search ecosystems.
